Hot on the heal of CBS buying Last.fm yesterday is eBay acquiring StumbleUpon.com today for $75M !

The question is ... why ? What's in it for eBay ? I supposed eBay can piggy-backing in StumbleUpon already excellent web-browser toolbar plug-in that everybody (meaning its users) love.

Here is quote from eBay's press-release:

"StumbleUpon is a great fit within our goal of pioneering new communities based on commerce and sustained by trust," said, Michael Buhr, senior director, eBay. "StumbleUpon's downloadable toolbar provides an engaging and unique experience to its users, but it is the similarities in our approaches to the concept of community that make it such a compelling addition to eBay."

Anyway, congrats for the guys at StumbleUpon !
